• WPF calls not working during long method processing

  - by Colin Rouse

  Hi, The following method does not apply the wpf changes (background = red) until the 2nd method (DoWork) exits: private void change() { Background = Brushes.Red; Dispatcher.BeginInvoke((Action) DoWork); } DoWork() takes several seconds to run and I don't really want to put it into a thread, as this code will be used in several places and will probably interact will the Dispatcher thread at various intervals. I've tried calling the Invalidate...() methods, but to no avail. The BeginInvoke() was added to see if the delay would allow the background change to be applied before the logic was called. Typically, the logic would be part of this method. Btw, most of the logic is performed on a different thread and shouldn't block the Dispatcher thread?! Can someone please help? Thanks

• Problem with "scopes" of variables in try catch blocks in Java

  - by devoured elysium

  Could anyone explain me why in the last lines, br is not recognized as variable? I've even tried putting br in the try clause, setting it as final, etc. Does this have anything to do with Java not support closures? I am 99% confident similar code would work in C#. private void loadCommands(String fileName) { try { final BufferedReader br = new BufferedReader(new FileReader(fileName)); while (br.ready()) { actionList.add(CommandFactory.GetCommandFromText(this, br.readLine())); } } catch (FileNotFoundException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } finally { if (br != null) br.close(); //<-- This gives error. It doesn't // know the br variable. } } Thanks

• StremReader.ReadToEnd() returning an empty string

  - by axk

  I have a method private static String DecompressAndDecode(byte[] data) { GZipStream decompressor = new GZipStream(new MemoryStream(data), CompressionMode.Decompress); StreamReader decompressed = new StreamReader(decompressor, Encoding.UTF8); String result = decompressed.ReadToEnd(); return result; } I have some GZipped text as input and the result is supposed to be a String representation of this text. The problem is that the method returns an empty string. What is puzzling me is that when I step trough the method in debug mode and reach the return statement the result variable is an empty string but if I create a watch for the decompressed.ReadToEnd() expression it returns me the text. What I would expect at this point is the result variable to contain the text and the decompressed.ReadToEnd() expression evaluating to an empty string. (Reevaluating the decompressed.ReadToEnd() expression returns an empty string as expected). There must be something obvious I'm missing here.

• Objective-C: Protocols

  - by Stu

  I'd like an instance variable object to adopt a protocol. @interface GameScene : Scene <AVAudioPlayerDelegate> { @private Layer *content <CocosNodeOpacity>; } For example I'd like my Layer object to adopt the <CocosNodeOpacity> so that I can get the methods -(GLubyte) opacity; //and -(void) setOpacity: (GLubyte) opacity; for free. The syntax shown above is invalid. Is it possible to achieve this without creating a new implementation file and creating a custom object? Thanks.

• Using a Session Scoped Bean

  - by jboyd

  The following code is returning null: private MyAppUser getMyAppUser(HttpSession session) { MyAppUser myAppUser = (MyAppUser) session.getAttribute("myAppUserManager"); return myAppUser; } Despite the fact that I have the following in my context: <bean id="myAppUserManager" class="com.myapp.profile.MyAppUser" scope="session"/> This doesn't make any sense to me, the "myAppUser" bean is a bean that absolutely can never be null, and I need to be able to reference it from controllers, I don't need it in services or repositories, just controllers, but it doesn't seem to be getting stored in the session, the use case is extremely simple, but I haven't been able to get to the bottom of what's wrong, or come up with a good workaround

• ANDROID. Emulate Hardware Keys with an IME. Doesn't work with Dialog and Spinner

  - by shutdown11

  I have understand that the only way to inject KeyEvents in the Android System is to implement an Input Method. I have created my IME with the purpose to control from remote the device. I emulate the hardware keys using the method private void keyDownUp(int keyEventCode) { getCurrentInputConnection().sendKeyEvent( new KeyEvent(KeyEvent.ACTION_DOWN, keyEventCode)); getCurrentInputConnection().sendKeyEvent( new KeyEvent(KeyEvent.ACTION_UP, keyEventCode)); } in my class that extends InputMethodService. It works fine until an AlertDialog, or the menu of a Spinner comes in foreground. Also the windows that appears when the Menu key is problematic. My IME can't get focus on them, and the keyevents are sent to the activity behind them. Using hardware keys, the Dialog get the focus and you can select the botton on the Dialog. How can i emulate that, using the IME(or anything else)?

• How do I customise date/time bindings using JAXWS and APT?

  - by Jordan Digby

  Im using JAXWS 2.1.7, using some classes to run through JAXWS's 'apt' to generate the WSDL. For dates, I use @XmlSchemaType(name="time") private Date wakeupTime; and this generates a schema with xs:time, but when this all comes out in XML, the value is something like <wakeupTime>1901-01-01T01:00:00 +10</wakeupTime> I want JUST the time portion to come! I think I want to use a custom converter to say that xs:time + java.util.Date should be printed and parsed in such-and-sucha manner, but I cant see that I can pass a bindings file to the apt routine. I can't (for historical & other reasons) use XMLGregorianCalendar - it has to be a java.util.Date. How do I specify a custom binding for the apt tool in jaxb

• trying to find if a file exists in a given path

  - by Yeshwanth Venkatesh

  I am fairly new to java and I am trying to find if the file specified in the LINUX path exists. private void validateFilePath(String filePath) { File dir = new File(filePath); if(dir.exists()){ System.out.println("File exists in the path " + dir); setTARGET_IMG_DIR("filePath"); return; }else{ System.out.println("File does not exists in the path: " + dir); return; } } The dir.exists works fine if I give a absolute path from my root like this /Users/yv/Documents/Eclipse-workspace/InputParser/bin/test.txt but if I give a relative path like test.txt or /InputParser/bin/test.txt it says files does not exists. I am planing on creating a jar of this projects and hence this should work with both relative path(files in the same directory) and absolute path from the root. How can I handle this ? Is it possible to search for the absolute path of that file from the root and append it to the file name ?

• Adding dynamic controls to Silverlight application after WCF Service Asynchronous Callback

  - by Birk

  I'm trying to add some dynamic controls to my Silverlight page after a WCF call. When I try to add a control to I get an error: Object reference not set to an instance of an object. Here is a simplified version of my code: using edm = SilverlightBusinessApplication.ServiceRefrence; public partial class ListWCF : Page { edm.ServiceClient EdmClient = new ServiceClient(); public ListWCF() { EdmClient.GetTestCompleted += EdmGetTestCompleted; EdmClient.GetTestAsync(); } private void EdmGetTestCompleted(object sender, edm.GetTestCompletedEventArgs e) { //This is where I want to add my controls Button b = new Button(); LayoutRoot.Children.Add(b); //Error: Object reference not set to an instance of an object } } Is it not possible to modify the page after it has been loaded? What am I missing? Thanks

• Get All Users in an Active Directory Group

  - by Matt Hanson

  I'm using the following code sample to get a list of all users in a specified AD group (in this case, all users in the "Domain Users" group). My listed code works great, with one exception: it won't return users who have their primary group set to "Domain Users". How can I get a list of all users in the group, including those who have it set as their primary group? Private Sub GetUsers() Dim groupSearcher As New DirectorySearcher Dim groupSearchRoot As New DirectoryEntry("LDAP://OU=Users,DC=domain,DC=com") With groupSearcher .SearchRoot = groupSearchRoot .Filter = "(&(ObjectClass=Group)(CN=Domain Users))" End With Dim members As Object members = groupSearcher.FindOne.GetDirectoryEntry.Invoke("Members", Nothing) For Each member As Object In CType(members, IEnumerable) Console.WriteLine(New DirectoryEntry(member).Name.Remove(0, 3)) Next End Sub

• C# Changing a constant

  - by Jane T

  I have inherited a small windows form based program written in C# that uses a 'constant' (See below), I need to modify this program so 'PROPERTY_NAME' can be "jobs" and "careers". private const string PROPERTY_NAME = "jobs"; I'm guessing a constant isn't designed to change so should I need to change this. The line above is set once at the top of a class file and then PROPERTY_NAME is used throughout that file. On the main form I would like to add two radio buttons 1 called 'jobs' and one called 'careers' and then change the PROPERTY_NAME in the class file based on which is selected. Would I need to pass the radio button status to the method in the class file? I recall reading that I can't simply read the radio button value from the class file. Many thanks for your advice. Jane

• Webwork actions, the lifecycle of variables declared in the action class.

  - by Sam

  Hi all, I'm using the webwork framework (JIRA plugin development) and was wondering about the lifecycle of the variables in the action class. I have a few private variables in the action class that are set when during the doDefault() method. These are used in the input view to set up jqGrid columns and then when the user has entered some data they click submit which puts the grid data into a hidden input. The next thing that happens is the doValidation() method is called before the doExecute(), which displays the input view if there are any errors. The problem is that the variables set up in the doDefault() method are now null. Can anyone explain to me how the lifecycle of variables works in the webwork actions? Cheers

• Constructor invocation returned null: what to do?

  - by strager

  I have code which looks like: private static DirectiveNode CreateInstance(Type nodeType, DirectiveInfo info) { var ctor = nodeType.GetConstructor(new[] { typeof(DirectiveInfo) }); if(ctor == null) { throw new MissingMethodException(nodeType.FullName, "ctor"); } var node = ctor.Invoke(new[] { info }) as DirectiveNode; if(node == null) { // ???; } return node; } I am looking for what to do (e.g. what type of exception to throw) when the Invoke method returns something which isn't a DirectiveNode or when it returns null (indicated by // ??? above). (By the method's contract, nodeType will always describe a subclass of DirectiveNode.) I am not sure when calling a constructor would return null, so I am not sure if I should handle anything at all, but I still want to be on the safe side and throw an exception if something goes wrong.

• NHibernate session management in ASP.NET MVC

  - by Kevin Pang

  I am currently playing around with the HybridSessionBuilder class found on Jeffrey Palermo's blog post: http://jeffreypalermo.com/blog/use-this-nhibernate-wrapper-to-keep-your-repository-classes-simple/ Using this class, my repository looks like this: public class UserRepository : IUserRepository { private readonly ISessionBuilder _sessionBuilder; public UserRepository(ISessionBuilder sessionBuilder) { _sessionBuilder = sessionBuilder; } public User GetByID(string userID) { using (ISession session = _sessionBuilder.GetSession()) { return session.Get<User>(userID); } } } Is this the best way to go about managing the NHibernate session / factory? I've heard things about Unit of Work and creating a session per web request and flushing it at the end. From what I can tell, my current implementation isn't doing any of this. It is basically relying on the Repository to grab the session from the session factory and use it to run the queries. Are there any pitfalls to doing database access this way?

• How to sort list items for Date field value (Apex, Salesforce)

  - by Channa

  With Salesforce's Apex, is there any way to sort list items, for Date field value. Please refer the TODO section of the following code, thanks. /** * Select list of jobOccurrences belongs to particular list of jobs */ private List<Job_Occurrence__c> getJobsByJobCode(List<Job__c> jobList) { // Select relevant Job Occurrence objects List<Job_Occurrence__c> jobOccuList = new List<Job_Occurrence__c>(); for (Job__c job : jobList) { Job_Occurrence__c jobOccurrence = [SELECT Id, Job__c, Schedule_Start_Date__c FROM Job_Occurrence__c WHERE Job__c =: job.Id]; if((jobOccurrence != null) && (jobOccurrence.Id != null)) { jobOccuList.add(jobOccurrence); } } if((jobOccuList != null) && (jobOccuList.size() > 0)) { // TODO // How I sort the 'jobOccuList' with Date field 'Schedule_Start_Date__c', // for select the items according to sequence of latest jobOccurrence return jobOccuList; } else { throw new RecordNotFoundException ('Could not found any jobOccurrence for given list of jobs'); } }

• var keyword without 'using someNamespace'

  - by RichK

  How does Visual Studio/intellisense know what to do with a variable declared as var even if you don't include the necessary using declaration at the top? For example, I have class MyDomainObject defined in a different namespace If I don't declare using TheOtherNameSpace; in the file the following code won't compile: private void Foo() { MyDomainObject myObj = new MyDomainObject(); // Doesn't know what this class is } But if I use var var myObj = new MyDomainObject(); This will compile, and intellisense knows exactly what I can with it. So how the heck does it know what the type is without the using? (And as an aside, if it knows without the using, why do we need usings at all?!)

• ListAdapters and WrapperListAdapter algorithm

• Android file-creation fails.

  - by Alxandr

  I use the following code to create a folder "mymir" and a file ".nomedia" (in the mymir-folder) on the sdcard of an android unit. However, somehow it fails with the exception that the folder the ".nomedia"-file is to be placed in dosn't exist. Here's the code: private String EnsureRootDir() throws IOException { File sdcard = Environment.getExternalStorageDirectory(); File mymirFolder = new File(sdcard.getAbsolutePath() + "/mymir/"); if(!mymirFolder.exists()) { File noMedia = new File(mymirFolder.getAbsolutePath() + "/.nomedia"); noMedia.mkdirs(); noMedia.createNewFile(); } return mymirFolder.getAbsolutePath(); }

• Flex 3: Embedding MovieClip Symbol to Image Control programmatically

  - by BlueDude

  I've reviewed all the documentation and Google results surrounding this and I think I have everything setup correctly. My problem is that the symbol is not appearing in my app. I have a MovieClip symbol that I've embedded to my Flex Component. I need to create a new Image control for each item from my dataProvider and assign this embedded symbol as the Image's source. I thought it was simple but apparently not. Here's a stub of the code: [Embed(source="../assets/assetLib.swf", symbol="StarMC")] private var StarClass:Class; protected function rebuildChildren():void { iterator.seek( CursorBookmark.FIRST ); while ( !iterator.afterLast ) { child = new Image(); var asset:MovieClipAsset = new StarClass() as MovieClipAsset; (child as Image).source = asset; } } I know the child is being created because I can draw a shape and and that appears. Am I doing something wrong? Thank you!

• How can I have a serializable struct that wraps it's self as an int32 implicitly? in C#?

  - by firoso

  Long story short, I have a struct (see below) that contains exactly one field: private int value; I've also implemented implicit conversion operators: public static implicit operator int(Outlet val) { return val.value; } public static implicit operator Outlet(int val) { return new Outlet(val); } I've implemented all of the following : IComparable, IComparable<Cart>, IComparable<int>, IConvertible, IEquatable<Cart>, IEquatable<int>, IFormattable I'm at a point where I really have no clue why, but whenever I serialize this object, I get no value. For instance, with XmlSerialization: <Outlet /> Also, I'm not solely concerned about XmlSerialization, I'm concerned about ALL serialization (binary for instance) How can I ensure that this serializes properly? NOTE: I did this because mapping an int,int dictionary seemed rather poorly typed to me when explicit objects with validation behavior were desired.

• Copy and Store LPTSTR in class causes crash

  I am attempting to copy a LPTSTR and store that string as a member variable in an object. But my attempts to copy the LPTSTR seem to fail and when I go to access/print the value of the copied LPTSTR I get a program crash. Is it possible to copy a LPTSTR and store it in my class below or is it better to just use a TCHAR*? class Checkbox { private: LPTSTR text; HWND hwnd; public: Checkbox(HWND nHwnd, LPTSTR nText) { lstrcpy(checkText, text); } void print() { // Causes a crash MessageBox(hwnd, text, text, MB_OK); } };
